' Referring to the drawings, Figure 1 indicates the forward portion of an-automobile, the engine being indicated at 1, the intake the box cap -manifo1d'at 2, the carburetor at 3, the carburetor'feed-pipeat 4.- The control box is indicated at 5. From the control box a conduit 6 leads to the shutter support 7 intermediate the carburetor and the intake manifold. A second conduit 6 leadsfrom 'the control box to the rear of the chassis for con nection with the main fuel tank, as shown in Figure 8. i Any suitable'means may be employed for shutting off the flow of gases from the caruretor to the manifold. In the present embodiment Iemploy a shutter support, the

1 lower member of which is illustrated in detail in Figures 2 and 3. The shutter support comprises a sh allow lower member 8 and a cap member 9* (Figure 7-). Each member is formed with an opening for the passage of gases, the opening of one member being in register with the other, and the opening of the lower member being indicated at 9, Figures 2Iand 3. The depending extension 2 of the manifold is formed with a flange 10 and the connectin pipe 11 for the carburetor port is placed intermediate flanges 10 andv 12 and is olted thereto by means of the bolts 13', Within chamber 8 of the shutter holder is a shutter 14 pivoted-at 15 and having a lever arm 14* to which is connected a spring 15 tending to. move the shutter into its closed position, as shown in Figure 2. tThe shutter is adapted to be moved into openvposition by means of a rod ,or cable 16 connected to the and extending through conduit 6 to the control box 5.

Within the control box is a lever arm 17 pivotally mounted on a stud shaft 18. Lever arm 17 is adapted to be swung by means of a cam'mem'ber 18 mounted on a shaft 19 which extends, from end to endof the control box and has secured thereto an operating handle 20. Cam member 18 is provided with two cam projections for lever 17, these-projections being indicated at aand b; sothat'movement of the handle 20 to either the right or to the left from its neutral position will cause a movement of rod 16 and act to open the shutter 14, thus permitting theflow of gases from the carburetor to the engine.

Within the control box 5 and fixed to stud shaft 19 is a second lever 21, connected at its lower end to a rod 22, the latter passing through conduit 6 and beingconnected at its other end to a dog 23 adapted to engage a shoulder 24 on cap 25 for the main fuel tank. 26. when said cap is moved into closing posi-- tion. Any suitable cap or plug for the filler opening of the tank may be employed, it only being necessary that the rod 22 be connected with some operative retaining device for-the cap. Lever 21 is in line with'a cam projection 0 on cam member 18*, which projection is in line with projection 7). Thus movement of operating lever 20 in a predetermined direction will enable the springs to actuate levers 17 and 21, simultaneously closing shutter 14 intermediate the carburetor and the manifold and will lock the filler cap in posi tion at the main supply tank,'thus effectively stopping the running of the car.

If an attempt ismade to open the manifold shutter by sawing through conduit 6 and i formed in the margin of the shutter 14 thereby holding the same against movement in anv direction. The lower end of pin 6 is bevelled and this enables a bevelled face 14 to engage and raise the pin when the shutter is moved from the open position shown in Figure 3 to closed position shown in Figures 2 and 5.

Should an attempt be made to remove the retaining dog from the filler cap by sawing through conduit. 6". this will be inefiectual for the following reasons The filler cap housingis formed with an apertured extension 28, the rod passing 7 through the aperture of the housing and through a small aperture formed in a plu 29. Surrounding the rod and having one end bearing against plug 29 and the opposite end against the dog 23 is a coil s ring 30. An":

suitable connection may be made intermediate housing extension 28 and conduit 6 as, for exv ample, the coupling 31. Reference to Figure 8 will show that when the dog 23 is in retain ing position it has not moved to its maximum position, being held against such movement by rod 22. Should conduit 6 be severed, rod 22 will be released and spring 30 will thereupon throw the dog to the right whereupon a pin 32 disposed within the cap housing-will fall down into an aperture 33 formed in the dog, therebv preventing movement of the dog in any direction.

A key lock is provided for. locking the handle 20 in position so that the rods 16 and 22 cannot be operated to open the shutter or to release the filler cap, thus aflording a double insurance against unauthorized operation of the car or the theft of motor fuel from the tank.. Such locking means is as follows Within the control box 5, adjacent stud shaft 19, which shaft is squared, is a locking plate 34 which is normally maintained in upper position by means of a spring 35, the spring acting against an arm 34 on the plate. The plate is guided in its movements by a ide projection 36 which passes within a vertical slot 37 formed in the plate. the plate is in upper position handle 20 can- When 9 not be moved. When an attemptis made to rotate the handle. stud shaft 19 strikes the edge of the plate and cannot move farther.

When thelocking plate is moved to its lower position, as shown in Figure 9, the handle can be moved because of its being given clearance through the recessing of the wall of the plate as at 34*". Looking plate 34 may be moved downward by any suitable means, controlled by a key, the means shown consisting of an arm 38 carried by a spindle 39, thespindle being controlled and rotated through a key, the key passing into a slot 40. The specific construction of the lock and its operating member for thelocking plate forms no part of the present invention and does not require specific illustration or description, it being sufficient to provide any standard form of lock so arranged as to have a member adapted to depress the locking plate 34.

In some cases it may be desired to shut the fuel oflf from the vacuum tank. In Figure 8 I have indicated the vacuum tank at 41, and at 42 a pipe leading to the carburetor. Intermediate pipe42 and the vacuum tank is a connecting box 43 and within the box is a valve member 44 of any suitable construction adapted to shut off the flow of fuel from-the vacuum tank to pipe 42. Box 43 is connected with control box 5 by means of the pipe 6 which, in the other figures, is connected to Having described my invention what I claim and desire to secure by Letters Patent is as follows 1.
